WATER-TRAP.

SPECIFICATION forming part of Letters Patent No. 249,031, dated November 1, 1881.

Application filed June 3, 1881.

To all whom it may concern:

Be it known that 1, WILLIAM J. ENGLISH, a citizen of the United States, residing at Gohoes, in the county of Albany and State ofNew York, have invented new and useful Improvements Water-Traps, of which the following is a specification.

This invention relates to improvements in that class of water-traps which are known as S-traps, and the objects of my invention are to lessen the labor of making the connections.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a central section of my trap. Fig. 2 is a transverse section in the plane a; 00, Fig. 1. Fig. 3 is a longitudinal sectioniu the plane 3 y, Fig. 1. Fig. 4 is an end view of the mouth of my trap. Fig. 5 shows my trap connected to an inclined pipe.

Similar letters indicate corresponding pal ts.

In these drawings, the letter A designates my trap, which is composed of three limbs, a b c, nearly parallel to each other and connected to each other by the crooks d e.

The free end of the limb a, which forms the mouthf of my trap, and the free end of the limb c, which forms the discharge-opening g,

are brought in such a position that they are in line with each other, so that it my trap is inserted into a pipe the delivery part of this pipe will remain in line with its discharge part, and consequently the operation of making the connections'will be materially facilitated.

The middle limb, b, of my trap is provided with an enlargement or chamber, h, (see Figs. 2 and 3,) the object or which is to retain a quantity of air and to prevent the trap from being siphoned out.

This improvement is applicable to S traps of every description, which, as is a well-known fact, are liable to become siphoned out it a strong current of water is caused to pass through them. This difficulty is avoided by the chamber it, since a portion of the air which is carried down into the trap with the water is caught in the chamber h, and if the supply of Water stops the draft produced by the discharging current empties the trap down to the chamber h; but as soon as the air contained in said chamber is liberated the suction stops and the trap cannot be siphoned out.

The mouth f of my trap is provided with outward] y-projectin g lips i, and with it is com- (No model.)

bined a ring, B, which is provided with recessesj and with outwardly-projecting slotted arms 7c.

The recessesj correspond in number and position to the lips i, so that the ring can be dropped over the mouthf, and that by turning it round it can be used to connect the trap to the bottom of a sink, 0, or to any other article of a similar nature.

The screws m, which serve to make the connection, pass through the slotted arms It. (See Fig. 1.)

It will be noticed that the ring B can be turned in either direction, so that the slotted arms can be brought into the most convenient position to make the desired connection.

The waste-pipe l is connected to the discharge end g of my trap by any suitable means.

If my trap is placed in such a position that the limbs or b c are upright, the discharge end 9 is still lower than the inletf and the seal is maintained.

Moreover, if my trap be turned from the position shown part way or less or more of the way round in a vertical plane, it will be found that a deep seal is presented at any point to which the trap may be turned 5 hence this trap is adapted for pipes running either in vertical or inclined planes.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The water-trap consisting of three substantially parallel limbs, a, b, and 0, connected by two bends, d and c, as described, the mouth of the limb a and the discharge-opening of the limb 0 being in line with each other, whereby the trap can be turned at any angle in a vertical plane and a deep seal still be preserved, substantially as set forth.

2. The water-trap consisting of the three substantially parallel limbs, a, b, and 0, communicating through two bends, d and e, the limb b being interposed between the limbs a and c, and formed with a laterally-projecting Witnesses WM. H. SMITH, J AS. H. PYNEs.
